Lockheed Martin's P-791 Airship is shown in its first flight in Palmdale in January 2006. The airship was a precursor to Lockheed's new a 290-foot airship, called SkyTug, that will be sold to the commercial market. The first SkyTug will be similar to a "super-sized helicopter" capable of carrying 20 tons of cargo.
